As part of the BBC World Service’s “What if…?” season, biologist Dr Andrew Holding meets some of the people straddling the line between man and machine.Over 50 years ago the term cyborg was first used to describe a person whose capabilities are augmented by mechanical or cybernetic parts.Today, mechanical or electronic prosthetic limbs and organs are rapidly changing more and more of our lives. But how far can it, and will it, go? Andrew meets some of those who might describe themselves today as a cyborg. Our bodies are not permanent, and if we lost a limb or an organ, and if we could afford it, we might well think about replacing it with a new device. But what about replacing a perfectly healthy part of your body with a device to give you superhuman powers? What if we could all become cyborgs?
